 by Johann Christoph Weigel, a publisher who had worked with Pachelbel before. The frontispiece, created by Cornelius Nicolaus Schurz, describes the collection as "six arias to be played on the organ, or the harpsichord, to whose simple melodies are added variations for the pleasure of Friends of the Muses." The instruments mentioned are referenced on the frontispiece: two cherub

 might study with one of them (it is unknown whether this hope was realized). Pachelbel also confesses that "something weightier and more unusual" than this work should have been written for the occasion, apparently feeling that this is not his best work. Pachelbel alludes to the "friendly nature" of Buxtehude and Richter, which might indicate that he knew one of them or both, perhaps through correspondence.

Another topic discussed in the preface is the nature of music. Pachelbel writes that music is the finest of the arts, governing human emotions and desires, and expresses the "belief of many" that music comes from the "Dreymal-Heilig" sung by angels and from the movement of celestial bodies (a belief, Pachelbel points out, shared by Pythagoras

Analysis

The collection contains six arias with variations, all on original, secular themes. The practice of composing variations on original themes was a relatively new one (one previous instance was Frescobaldi

A child prodigy, Frescobaldi studied under Luzzasco Luzzaschi in Ferrara, but was influenced by a large number of composers, including Ascanio...

 was one of the main exponents of this trend), and Pachelbel was among the first in Europe to explore the form. The overall plan of Hexachordum Apollinis is as follows:
Piece Key Number of variations
Aria Prima D minor 6
Aria Secunda E minor 5
Aria Tertia F major 6
Aria Quarta G minor 6
Aria Quinta A minor 6
Aria Sexta Sebaldina F minor 8

There is a distinct border between the first five arias and the last one. The first five are arranged so that their keys span a perfect fifth, the keys of a hexachord

 and all but one have 6 variations. According to the old hexachordal principle the sixth aria should've been in B-flat major. Pachelbel does use two flats, as expected, but the work is in F minor. Furthermore, this aria is in triple time and followed by 8 variations. Finally, it has a subtitle, Aria Sebaldina, referring to St. Sebaldus Church

 in Nuremberg, where Pachelbel was working at the time.

Pachelbel's themes are simple song-like pieces in two sections: four bars in the first section and four or eight in the second. Both sections are repeated. The variations conform to the same structure. Most are in common time (except for Aria Sebaldina, in which all variations are in triple time, like the theme) and explore various constant harmony and melodic outline models. Although the frontispiece indicates that the work is intended for either organ or harpsichord, much of the music is better suited for the latter, particularly the brisé figurations, broken chords, and a number of variations that introduce various non-keyboard styles: the strumming of a plucked string instrument, lute style brisé
